The particles would be more scattered out as those three factors increase.
Answer: If I have 17 moles of gas at a temperature of 67°C, and a pressure of 5.34 atmospheres, what is the volume of the gas? write down all the givens of the problem
Answer:
1.81 x 10²⁴atoms
Explanation:
Given parameters:
Number of molecules = 3 moles
Unknown:
Number of atoms = ?
Solution:
To solve this problem, we are going to use the mole concept.
1 mole of any substance contains 6.02 x 10²³ atoms
So
3 mole of propanone will contain 3 x 6.02 x 10²³ atoms = 1.81 x 10²⁴atoms

He saw a series of walled boxes that reminded him of the tiny rooms, or cellula, occupied by monks.
Answer:
the sodium nitrate in this investigation is
a) the solute
b) undergoing chemical change
<h3>
Explanation:</h3>
generally, solute is the substance which is added in solvent.
The substance which is taken in relatively more volume is the solvent.
so, here sodium nitrate (NaNO₃) is the solute which is dissolved in water (H₂O) , which is solvent.
The reaction between them is :
NaNO₃ + H₂O ⇒ Na⁺ (aq) + NO₃⁻ (aq) ; (aq) denotes aqueous;
so, here sodium nitrate undergoes chemical change into aqueous sodium ions(Na⁺) and aqueous nitrate ions(NO₃⁻).
